I really like the way a Pulse flies, but they are just not that tough. They are fine if you can do 100 landings in a row without hitting the prop, but since they are mostly lite ply so much is cut away to make a lightweight model. But they do fly as well as a classic design, a personal favorite of mine, the Andrew Trainermaster. A similar flying model was the old Sportster series, though they were at least a 1/2 pound heavier than the Andrew design.
